Bug: 51441
Change-Id: I9c09b84d3652449d3328586332c636a7a676273a
Changelist:
*removed backwards-compatibility code
*used HTML5 data attributes to store various information that we access in the JS file
*incremented the extension's version number
*removed ancient vote key stuff (the "vote key" was being passed to the AJAX function but it wasn't used in any of the functions)
*updated Linker class, that class is now static
*killd $wgTitle
Some things are now a bit slower, i.e. if you click on the green voting box, then click again when the unvote link appears, it doesn't seem to change back to "vote" again...but at least it should work now.
